Tutorial #1
There are many kinds of guitars. In this tutorial I am going to show you just the basic ones.As you all know the guitar produces the sound by the vibration of the strings. However, because the string can only displace a small amount of air, the volume of the sound needs to be increased in order to be heard. In an acoustic guitar, this is accomplished by using a soundboard and a resonant cavity, the sound box. The body of the guitar is hollow. The vibrating strings drive the soundboard through the bridge, making it vibrate. The soundboard has a larger surface area and thus displaces a larger volume of air, producing a much louder sound than the strings alone

2. Electric Acoustic Guitar
An electric acoustic guitar (or elecoustic for short) is by design an acoustic guitar fitted with pickups, a microphone or transducers. In electric acoustic guitars, the transducers and microphones are always used because conventional pickups are not capable of picking up vibrations of non-magnetic materials. The term is not synonymous with that of a semi-acoustic guitar, which is conceptually an electric guitar but with the addition of sound chambers within the guitar body.
3. Electric Guitar
An electric guitar is a guitar that uses the principle of electromagnetic induction to convert vibrations of its metal strings into electric signals. Since the generated signal is too weak to drive a loudspeaker, it is amplified before sending it to a loudspeaker. Since the output of an electric guitar is an electric signal, the signal may easily be altered using electronic circuits to add color to the sound. Often the signal is modified using effects such as reverb and distortion.
